(2) The one-way clutch according to claim 1, wherein the elastic member and the plurality of sprags are integrally molded from the same synthetic resin or elastomer. (3) The one-way clutch according to claim 1, wherein the plurality of sprags are made of metal, and the metal sprags are inserted into the elastic member made of synthetic resin or elastomer when the elastic member is molded. . (4) Any one of claims 1 to 3, wherein the outer ring has a function as a radial bearing by sliding the inner peripheral edge of the inward flange formed at the open end of the outer ring to the outer peripheral surface of the inner ring. One-way clutch described in Crab. (5) A one-way clutch according to any one of claims 1 to 4, wherein the shaft instead of the inner ring is arranged concentrically with the outer ring.
